NESticle

NESticle is a Nintendo Entertainment System emulator, which was written by Icer Addis of Bloodlust Software. Released on April 3, 1997, the widely popular program originally ran under MS-DOS and Windows 95. It was the first freeware NES emulator, and became commonly considered the NES emulator of choice for the 1990s. Initially offering few features and only supporting a handful of games, development proceeded rapidly and to expand usability such that NESticle is today credited with introducing the concept of recordable playthrough for emulation, as well as providing the capacity for users to create their own graphical hacks via an integrated graphics editor. In pioneering this heightened level of access for users, and providing the tools for fans to hack and remix familiar classics, NESticle has been credited by Spin as representing a milestone toward the development of video game music as a genre. While the emulator is no longer updated and has become obsolete as other emulation projects have developed and improved, NESticle remains frequently listed among prominent top tier emulators and it is still regarded as a good choice for emulation on older (486 and earlier) computers. In January 2022, the source code for a Super NES version of the emulator, SNESticle, was released by Addis after a programmer attempted to reverse-engineer the code, which had been released in a GameCube game, Fight Night Round 2. In February of that same year, Addis began work on a follow-up to NESticle, an experimental macOS-based application based on transistor-level simulation of the NES chipset, called metalnes.
